Application filed June 2 8,

Z '0 allwhom it may concern:

Be it known that I, LAWRENCE B. Li: DUKE, a citizen of the United States, resid ingat Lawrence, county "of Van Buren, State of Michigan, have invented certain new and useful Improvements in Spraying Apparatus," of which the following is' a' specification i p This invention relates to improvements in spraying apparatus. I

It isnecessary forcert'ain diseases and pests to spray grape vines while in leaf and great difficultyhas been experienced in ef- Y fective'ly' doing thisas the leaves form a shieldorcovering whichprevents the spray from reaching the desired portions of the vines andleaves. p 1 I It is the" main object of this invention to provide an improved spraying apparatus which is effective in the spraying of grape vines and the like when in'lea'f. A further ob'jectis to'provide an improved spraying apparatus which may be used as an attachmentor' mounted "upon spraying equipment now quite commonlyused.

Objects pertaining to details and economies of construction and operation of my improvementswill definitely appear from the detailed description to follow.

'I-accomplishtheobjects of my invention by the devices and means described in the 'followingspecification. The invention is clearly defined and pointed out in-the claims. I p t A structure "which i'sa preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this application, in which: i

The flexible extensions of the fingers prevent injury to the vines, which, at certain seasons, are quite delicate on account of the tender new growth.

My improved spraying apparatus is very efiicient'and convenient to use.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

'1. In a spray apparatus, the combina-;

tion of a supporting frame, a vertically disposed spray pipe carried thereby and having a plurality of late-rally directed spray nozzles, a spreader comprising a vertically disposed head bar pivotally mounted on said frame in front of said spray nozzles,

fingers mounted on said head bar to swing in planes between said nozzles, said fingers comprismg rods having coverings of flexible tubing disposed with the ends of the tubing projecting beyond the ends of the rods providing flexible ends for the fingers, a spring for yieldingly supporting said spreader with its fingers in an outwardly projecting rearwardly. inclined relation, and means for limiting the outward swing of said fingers under the action of said spring.

2. In a spray apparatus, the combination of a supporting frame, a vertically "disposed spray pipe carried thereby and having a plurality of laterally directed spray noz- 'HLOS', a spreader comprising a vertically disposed head bar pivotally mounted on said frame in front of said spray nozzles, fingers mounted on said head bar to swing in planes between said nozzles, a spring for yieldingly supporting said spreader with its fingers in an outwardly projecting rearwardiy inclined relation, and means for limiting the outward swing of 'said"'finger's under the action of said spring.

'3. In a spray apparatus, the combination of "a pivotally mounted supporting frame provided with a handle, a spray element carried thereby, a spreader comprising a vertically "disposed head bar mounted on said frame in front of said spray element, fingers mounted said head bar, and a spring for yieldingly sup orting said "spreader with its fingers in an outwardly projecting relation relative 'to said spray element.

4. In a spray apparatus, the-combination of a supporting framefai spray element carried thereby, a spreader comprising a veron "said frame in front of said spray element, fingers mounted on said head bar, and a spring for yieldingly supporting said spreader with its fingers in an outwardly projecting relation relative to said spray element. p

5. In a spray apparatus, the combination of a frame, a sprayer mounted on the pivotal'ly outer end of said frame, a spreader pivotally mounted on said frame in advance of said sprayer and comprising a. plurality of fingers having flexible ends, and means for yieldingly supporting said spreader with its fingers in an outwardly projecting rearwardly inclined relation.

6. In a spray apparatus, the combination of a pi'vo'tally'mounted frame provided with a handle, a sprayer mounted on the outer end of said frame, a spreader pivotally mounted on said frame in advance of said sprayer and having a plurality of fingers, and means for yieldingly supporting said spreader with its fingers in an outwardly projecting rearwardly inclined relation.

7. In spray apparatus, thecombination of a sprayer, a pivotally mounted spreader having fingers comprising rods havin coverings of flexible tubing disposed wit h the ends of the tubing projecting beyond the ends of the rods providing fiexible ends for the fingers, and a spring for yieldingly supporting said spreader with its fingers in an outwardly projecting relation relative to said sprayer.

8. In a spray apparatus, the combination of a ivotally ,mounted spreader provided with a plurality of fingers having flexible ends, and means for yieldingly supporting said spreader with its fingersin an out- Wardly projecting rearwardly inclined relation relative to said sprayer.

'9. In a spray apparatus, the combination v of a sprayer, a pivotally mounted spreader tic'a'lly disposed head bar pivotally mounted provided with a plurality of fingers, and means for yieldingly supporting said spreader with its lingers in anoutwardly projecting rearwardly inclined relation relative to said sprayer.

In witness whereof, I have hereunto set my hand.
